The Gates heavy‑duty Micro‑V V‑ribbed belt for the 1999 Freightliner FLD with Cummins ISM diesel is specified for A/C routing as a heavy‑duty serpentine replacement. Sized to match the required rib profile and tensioner fit for that application, it offers increased durability and maintains correct engagement with A/C pulleys under the heavier loads encountered in commercial use.
